Polylane

Polylane is a production-oriented AI on-call agent whose core goal is to let software be handled before problems escalate into incidents, thereby reducing or even eliminating manual on-call duty. It connects your code, cloud accounts, and observability tools to proactively discover production issues and attempt automatic remediation.

1. Purpose Polylane gives software the ability to "self-operate": the AI agent learns everything you run, fixes the problems it can fix, reviews how code changes actually perform in production, answers questions encountered during on-call, and provides the same production context to coding agents. It is suited to fast-iterating software teams, especially small and medium-sized engineering teams.

2. Main capabilities

3. Threshold-free issue detection: Polylane continuously observes the logs, metrics, and traces of all services, learns what the "normal" state looks like, and raises an issue as soon as there is a deviation, without waiting for users to report a bug and without relying on manually set alert thresholds. Any metric the team has already charted can become a check.

4. Root cause investigation: For each issue, Polylane investigates across code, deployments, and telemetry data, showing what happened, why it happened, and the evidence supporting the conclusion. In the official website example, the root cause report updates with the evidence (such as "checkout-edge Latency Degradation (Recurring)").

5. Automatic remediation and Pull Requests: When the root cause is a code defect, Polylane writes the fix and automatically submits a Pull Request. For example, in the example, it queues an automatic fix, restores the configuration of the Hyperdrive connection pool hd-prod (restoring max_connections from 5 to 50), and adds a regression test that will fail when the connection pool is queued, and also configures the deployment target in wrangler.jsonc; then Boris gets a PR with deployable code, and after merging, running wrangler deploy replaces the problematic worker.

6. Incident triage and aggregation: The example shows that Polylane records and merges 118 alerts from Datadog monitoring into the same issue, determines that its P99 latency reaches 18 times its own baseline, lasts 12 minutes, and deviates from the "hour-week" baseline band, thereby triaging it as an incident.

7. Recurring issue tracking: For the same fingerprint, theissue, if it reappears after being resolved, will be detected again (in the example, it was quiet for 6 days and then triggered again).

8. Production context for coding agents: Polylane gives coding agents the same production context it has.

9. How to use

10. Installation: On macOS or Linux, run the command curl -fsSL https://polylane.com/setup | bash, to install the CLI, connect your coding agent, and create an account. The installation process performs a sha256 verification and installs the program to ~/.polylane/bin/polylane, and complete the login.

11. No migration, no new SDK: Polylane connects to the system you are already running; it requires no migration and no introduction of a new SDK.

12. Writes require approval: every write operation pauses and waits for your approval, and the exact request is displayed on the screen; code changes are delivered in the form of a Pull Request, gated by your review process and CI.

13. Developer interfaces: provides a REST API (api.polylane.com) and an MCP server (mcp.polylane.com/mcp); the website itself provides machine-readable content at polylane.com/llms.txt.

14. Connectable systems The officially listed connectable targets include: AWS, Cloudflare, Vercel, Fly.io, Render, Kubernetes, PlanetScale, Railway, Supabase, Modal, Convex, ClickHouse, Turso, as well as GitHub, Slack, and the observability tools Datadog, Honeycomb, Axiom, Grafana Cloud, Sentry, Better Stack, OpenStatus, Logfire.

15. Security and trust Polylane provides independently audited security controls and follows the international standard for information security management; data is encrypted at rest using AES-256 and in transit using TLS 1.2+; each organization is fully isolated. The official documentation also notes that AI can make mistakes and recommends carefully verifying the cited sources.

16.
